The All-Star has twice experienced an atrial fibrillation episode, otherwise known as an irregular heartbeat, while the Dodgers were in the high altitude of Colorado. It most recently occurred in August, when his heart had to be shocked back into a regular rhythm. He didn't travel with the team back to Colorado in September as a precaution.

Jansen underwent a heart procedure in 2012 to help the issue.

He said Friday while distributing holiday turkeys that if all goes well, he would be cleared in two weeks. But if doctors find anything abnormal, Jansen said he would be down for eight weeks although he could still do his offseason work to be ready for opening day.
